Abstract: An RF signal detection and switching system is disclosed. The system includes an output common line, an output primary line, and an output secondary line. The system also includes a first switch that interconnects the output primary line with the output common line when the switch is in a first switching state. The first switch also interconnects the output primary line with a first load when it is in a second switching state. The system further includes a second switch that interconnect the output secondary line with a second load when the switch is in a first switching state. The second switch also interconnects the output secondary line with the output common line when the it is in a second switching state. An analogous system is also disclosed for input lines.
